Thin Layer Spectroelectrochemical Studies of Cobalt and Copper Schiff Base Complexes in N,N-Dimethylformamide

Abstract

Since its initial development in 1967 (1), the optically transparent thin layer electrode (OTTLE) has seen increasing application to the spectroelectrochemical study of chemical compounds. The cell consists of a thin layer of electrolyte, typically 0.05–0.2 mm thick, which is confined adjacent to a transparent electrode. The advantageous features of such a cell are (a) rapid electrolysis (typically 20–120 sec) of the thin solution layer with diffusion as the only mode of mass transport to the electrode, and (b) simultaneous recording of spectra by an optical beam passing through the transparent electrode.
